[Asterisk-Users] Problem Using Asterisk Call Files with Zap PRI

Adam Robins arobins at PharmaCentra.com
Tue Apr 18 14:00:05 MST 2006


 
I have an application where I need to send outbound prerecorded
messages.  The Asterisk "call file" process works fine if I am sending
the call via SIP or IAX, but not via ZAP over a PRI channel.  The
destination device (my cell phone) never rings.  The only unusual thing
I see is on the fifth line of the "full" log, below, "channel.c: Don't
know what to do with control frame 15".  It never gets to the
auto_outbound context.  

Asterisk version is 1.2.4.

I appreciate any assistance you may provide.


Call File config:

Channel: ZAP/G1/1770xxxxxxx
Callerid:  CompanyName <800-111-2222>
MaxRetries: 1
Context: auto_outbound
Extension: s
Priority: 1
SetVar: file=recordingtoplay


Extensions.conf:

[auto_outbound]
exten => s,1,Answer
exten => s,n,Wait(1)
exten => s,n,Background(${file})
exten => s,n,Hangup


Full log output:
